The lens isn't designed to accept one. The knurled area is too close to the body, then there's the switches/distance window, and the bare part after that rotates (it's part of the focus ring, just not rubberized).

As a generic (but expensive) solution for non-collared lenses, you could look at Really Right Stuff's Camera Rotation Device. I think Custom Brackets has something like it, as well.

EDIT: Regarding simply finding a collar with the right diameter, lenses designed to take a collar have a 'flat' area for it. There are highly customized (and costly) solutions for some lenses - well, actually I'm only aware of one, the Hartblei collar for TS-E 17/24 lenses to eliminate parallax for shift panos), not aware of anything for the 135L.

I do not know tripod collar specific to 135L, but some may happen to be the same diameter. Try to measure the diameter of 135L where you fit the collar. Then search for information with sellers necklace for 100L, 200L, MP-E65. Good luck in the search.

Yes I thought this might be the case with the collar for the 135 f/2...no-go. Thanks for that.The L Bracket looks like a viable option. I'll check that out.

Another reason I think I reach for the 135 f/2 less often is the lack of IS. Maybe I don't have the steady hands that other more fortunate photographers are blessed with. IS is a tool that bumps my keeper rate way up.

This has got me thinking I should off-load the 135 f/2 and get a Canon EF 100mm f/2.8L Macro which can take a collar and has IS. Is the AF on the 100mm f/2.8L Macro quick? (Unlike my glacial old EF 100 macro from last century).

If there is a MkII 135 in Canon's future, IS and an optional collar would be appreciated.

Thought you had an L-bracket already, for some reason. It's not as fast as a collar, and a little cumbersome on a monopod, but definitely what I'd try first (and what I use with non-collared lenses).

The AF on the 100L is slower than the 135L and 70-200 II, and tends to hunt in dim light (it's an f/2.8 lens, but it's in Group C on the 1D X/5DIII - it doesn't activate any f/2.8 high precision points). Using the focus limiter helps, but it's not a total fix. If you depend on fast AF, it's not the best choice, IMO.

I have this mounted on my monopod and it comes in quite handy. Note that the plate does not change axis, so you can tilt forward/backwards w/lens plate and sideways only with camera plate (for portrait).
